Arctic F12 PWM PST CO (Black) Standard Fan, PWM

The PWM function allows the motherboard to run the fan precisely at its necessary speed. This ensures the required cooling and minimizes the noise level.

If you want to improve the cooling efficiency of your computer you get several case fans working in parallel (since it takes 10 fans to double the noise level). But what does it help if they don't work together? The PST assures that all of your fans listen to one control signal. E.g., you share the CPU cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary.

The innovative design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimizing the noise level yet delivering the desired airflow and pressure.

The premium-quality dual ball bearing allows continuous operation 24/7 without the slightest compromise in performance. Dust and high temperature are affecting this bearing a lot less than generic sleeve or one ball bearings and thus make it the perfect choice if reliability is key. The CO case fan's lifespan is longer.
